Getting screwed over on a payment for a parts purchase?

Is that the case these days? In years past the seller was the only one who could get punished for abusing the platform.
But that was from the days before china retailers took over the whole damn site.
I know that it's hard not to buy foriegn products as so much is made over seas. This is why I really have a hard time with buying Chinese made intake manifold and cylinder heads when edelbrock is made here, and are some of the afr heads. It's some of our own faults, as everyone wants everything cheaper. My dad knew a older guy that drove a hour to buy his clothes as they were union made in America.
